CARL SPRINGFELS, or BUFFALO, NEW YORK BOX.

Specification of Letters Patent.

Patented Dec. 18, 1m;

Application filed September 8, 191G. Serial No.,119,003

To all'whom it may concern:

Be it known that I, CARL SPRINGFELS, a

citizen of the United States, residing'at Buffalo, in the county of Erie and State of New York, have invented certain new and useful Improvements in Boxes, of which the following is a specification.

My invention relates to the class of boxes having a hinged cover, or lid, and which is provided with a spring serving'to hold the same in either a closed or open position.

The object of my invention is to provide a new and improved spring for spring lid boxes and especially jewelry boxes, and means to fasten same to the box and lid after they are covered.

This class of box is usually covered with plush, velvet or leather and then suitable backs or cushions inserted. By use of my improved spring and fastening, the box and lid may be covered separately by machinery and afterward fastened together.

In the accompanying drawings, illustrating the preferred form of my invention,

Figure 1 is a view in perspective of a box embodying my invention. Fig 2, is a sectional elevation of the closed box on a line CC of Fig. 3. Fig. 3, is a sectional elevation of the closed box and showing the hinge and spring. Fig. 4, is a side view of the spring and showing it in dotted lines in different positions. Fig. 5, is a sectional elevation of the open box on the line CC of Fig. 3. Fig. 6, is a dotted front elevation of the spring shown in detail in Fig. 4. Fig. 7 is a sectional view of the box on line BB of Figs. 3 and 5, showing the hinge and method of fastening to the box. Fig. 8, is a side view of the hinge and showing it in dotted lines in different positions.

Having reference to the drawings, there is shown a box commonly employed for holding jewelry. It comprises a lower partor box 2, and an upper part or lid 1, which are preferably constructed of light stamped sheet metal as 4' and 3, but may equally well be constructed of other suitable material. 5 and 6 represent a covering of plush or other similar or suitable material. 7 represents the hinge (see Fig. 8) on which are formed small lips or projections 8, 8, for retaining the spring 12 by means of the slots 16, 16. 9, 9, 9, and 9 (Fig. 3) represent slots in the hinge 7, and 15, 15 (Fig. 7)

similar slots in the box 2-for inserting the locking strips 11, to fasten the hinge? to the box'2 and lid 1., 10, 10, 10 and 10 are the endsof stripsll, 11 which are bentiover to retain the strips 11,11 in position as shown. No invention is claimed for the method of attaching the hinge 7 to the members of the box by meansof the locking strips 11.11, as the hinge may be attached to the membersby any one of various methods such as'ri'vets,solder, etc. i' V The. spring' l2 is vnorlnally of the shape shown in'Fig. 4 and having a substantial 7 right angle X to'hold the lid 1 in an open position as shownin Fig. 5, and l3 and 14.-

, rep re sent different positions of the spring 12 when the lid 1 of the box 2 is in a half closed and in a closed position. The hinge 7 is shown in Fig. 8 in the same position as in Fig. 5 where the lid is open and 17 and 18 represent different positions of the hinge 7 when the lid 1 of the box 2 is in a half closed and in a closed position.

The spring 12 and hinge 7 are shown ongaged in Fig. 5 as they are when mounted in a box, with the lid open, and with the lid closed in Figs. 2 and 3.

In my construction the locking strips 11, 11 are first inserted in the slots 15, 15 of the lid 1 and box 2, then the coverings 5 and 6 of the lid 1 and box'2 are put on and then the hinge 7 is fastened in place on the lid and box by inserting the locking strips 11 and 11, and ending over the ends 10, 10, 10 and 10. Th spring 1 is then put in place by inserting one of the lips 8 on the hinge 7 through one of the slots 16 in the spring 12 and half closing the lid 1 so the hinge 7 is in the position shown by dotted lines 17 (Fig. 8). The spring 12 is then straightened out until the ends are separated sufficiently for the other lip to be inserted inthe remaining slot 11.

The spring 12 is normally at rest as.

shown in Fig. 5 and holds the lid 1 of the box 2 open but is not exerting any pressure on the hinge 7 except as the lid 1 may I be moved. \Vhen the lid 1 is moved from the full open toward a closed position, the spring 12 exerts a pressure against this movement as the lower end of thespring is substantially pivoted while the upper end is moved and the spring straightened out until the lid is practically half closed and the spring and hinge are in the positions 13 and 17 as shown in Figs. 4 and 8. The hinge 7 is now opened on practically a straight line A A and the spring 4 is straightened so its ends are separated to the limit for the operation of the hinge. Continuing to close the lifcli the spring. 122. 110W" assists in the movement as its ends are moving toward each other to more nearly as- The reason ofthisisthat the, hinge, 7 is farthest .1 open: in.

sume its normal position.

pressure to'holdj itiin that positionas the.

spring is somewhat straightened" from its.

normal right angle position, as shown. in Fig. 2;

I have thus described away, of, "constructing andjusing my invention, without at: tempting to set forth all the forms in which it may be made-or all the modes of its.

use. Accordingly the claims. are; to. beinterpretedas contemplating such variations,
